Could you try the following:&lt;br /&gt;1. Update to the newest release of the&amp;nbsp;&lt;a href="https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Command-Line-Tools/Download"&gt;nRF Command Line Tools&lt;br /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;2. Run the command &amp;quot;nrfjprog --recover&amp;quot;&amp;nbsp;&lt;br /&gt;&lt;br /&gt;And report the results back to me?&lt;br /&gt;&lt;br /&gt;Best regards,&lt;br /&gt;Carl Richard&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
